Procurement Opportunities

SOS Historically Underutilized Business (HUB) Program

SOS actively promotes HUB participation in agency purchases of supplies, materials, services and equipment. We encourage HUB businesses to register with Texas Comptroller of Public Account (CPA). See CPA's Program site for the "how to's" of getting on the Centralized Master Bidders List (CMBL) and becoming HUB certified.
